A mortgage is typically the largest debt most Americans carry. Our mortgage calculator goes beyond the monthly principal and interest payment—it includes property tax, homeowners insurance, PMI, HOA fees, and extra payments so you see the true monthly cost of homeownership and your full amortization schedule.
A full mortgage payment is often called PITI: Principal, Interest, Taxes, and Insurance. It may also include PMI (if your down payment is under 20%) and HOA fees. Lenders typically escrow taxes and insurance as part of your monthly payment.
Conventional loans generally require a 620+ credit score. FHA loans accept scores as low as 580 with a 3.5% down payment, or 500–579 with 10% down. VA loans have no official minimum, though lenders typically want 620+.
A common guideline is the 28/36 rule: your monthly housing costs should not exceed 28% of your gross monthly income, and total debt payments should not exceed 36%. Lenders also look at your debt-to-income (DTI) ratio, typically capping it at 43%–45%.
Private Mortgage Insurance (PMI) is required on conventional loans when your down payment is less than 20%. Under the Homeowners Protection Act, lenders must automatically cancel PMI when your equity reaches 22% of the original home value. You can request cancellation at 20% equity.
A 15-year mortgage has higher monthly payments but much lower total interest—you build equity faster and typically get a lower interest rate. A 30-year mortgage has lower monthly payments, offering cash flow flexibility, but costs significantly more in total interest over the life of the loan.
Each point costs 1% of the loan amount and typically reduces your rate by 0.25%. To decide, calculate the break-even point: divide the upfront cost by your monthly savings. If you plan to stay in the home beyond that break-even date, points usually make sense.
